Differentiate between environmentally spread diseases and diseases that are spread from person to person.

A: Environmentally spread diseases are spread by physical contact of objects in the environment, such as the telephone, doorknobs, and soil, in which are covered with pathogens from those who are ill. Diseases that are spread from person to person, however, are spread through the air and by kissing, drinking from the same glass, engaging in sexual contact, and by touching objects the person who is ill has touched, sneezed, coughed upon?
